Add ACVP fips module tests

For FIPS validation purposes - Automated Cryptographic Validation Protocol (ACVP) tests need to be
performed. (See https://github.com/usnistgov/ACVP). These tests are very similiar to the old CAVS tests.

This PR uses a hardwired subset of these test vectors to perform similiar operations,
to show the usage and prove that the API's are able to perform the required operations.
It may also help with communication with the lab (i.e- The lab could add a test here to show
a unworking use case - which we can then address).

The EVP layer performs these tests instead of calling lower level API's
as was done in the old FOM.
Some of these tests require access to internals that are not normally allowed/required.

The config option 'acvp_tests' (enabled by default) has been added so that this
access may be removed.

The mechanism has been implemented as additional OSSL_PARAM values that can be set and get.
A callback mechanism did not seem to add any additional benefit.
These params will not be added to the gettables lists.

Refactor BN_R_NO_INVERSE logic in internal functions

Closes #12129

As described in https://github.com/openssl/openssl/issues/12129 the
readability of the internal functions providing the two alternative
implementations for `BN_mod_inverse()` is a bit lacking.

Both these functions are now completely internal, so we have the
flexibility needed to slightly improve readability and remove
unnecessary NULL checks.

The main changes here are:
- rename `BN_mod_inverse_no_branch()` as `bn_mod_inverse_no_branch()`:
  this function is `static` so it is not even visible within the rest of
  libcrypto. By convention upcase prefixes are reserved for public
  functions.
- remove `if (pnoinv == NULL)` checks in `int_bn_mod_inverse()`: this
  function is internal to the BN module and we can guarantee that all
  callers pass non-NULL arguments.
- `bn_mod_inverse_no_branch()` takes an extra `int *pnoinv` argument, so
  that it can signal if no inverse exists for the given inputs: in this
  way the caller is in charge of raising `BN_R_NO_INVERSE` as it is the
  case for the non-consttime implementation of `int_bn_mod_inverse()`.
- `BN_mod_inverse()` is a public function and must guarantee that the
  internal functions providing the actual implementation receive valid
  arguments. If the caller passes a NULL `BN_CTX` we create a temporary
  one for internal use.
- reorder function definitions in `crypto/bn/bn_gcd.c` to avoid forward
  declaration of `static` functions (in preparation for inlining).
- inline `bn_mod_inverse_no_branch()`.

Output that's supposed to be understood by a TAP parser gets its own

[crypto/ec] Remove unreachable AVX2 code in NISTZ256 implementation

`crypto/ec/ecp_nistz256.c` contained code sections guarded by a

The relevant comment read:

that this code has been basically unreachable without modifications to

CORE: make sure activated fallback providers stay activated

Calling 'OSSL_PROVIDER_available(NULL, "default")' would search for
the "default" provider, and in doing so, activate it if necessary,
thereby detecting that it's available...  and then immediately free
it, which could deactivate that provider, even though it should stay
available.

We solve this by incrementing the refcount for activated fallbacks one
extra time, thereby simulating an explicit OSSL_PROVIDER_load(), and
compensate for it with an extra ossl_provider_free() when emptying the
provider store.

TEST: Add provider_fallback_test, to test aspects of fallback providers

There are cases where the fallback providers aren't treated right.
For example, the following calls, in that order, will end up with
a failed EVP_KEYMGMT_fetch(), even thought the default provider
does supply an implementation of the "RSA" keytype.

    EVP_KEYMGMT *rsameth = NULL;

    OSSL_PROVIDER_available(NULL, "default");
    rsameth = EVP_KEYMGMT_fetch(NULL, "RSA", NULL);

For good measure, this also tests that explicit loading of the default
provider won't fail.
